UNITED STATES PATENT oFFIon REMUS E. TAYLOR, OF OAKLAND, KANSAS.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed January 12,1906. Serial No. 295,739.

To all whom it may concern.

Be it known that I, REMUs E. TAYLOR, a

citizen of the United States, residing at Oakland, in the county of Shawnee and State of Kansas, have invented new and useful Improvements in Machines for Molding Concrete Building-Stone, of which the following is a specification, reference being had to the accompanying drawings, which form a part thereof, and in which similar characters of ref erence denote like parts in all views.

The object of my invention is to provide an lmproved structure in the nature of a mold for molding building-blocks, particularly those made of cement or similar plastic material, and one so constructed that the blocks may be molded on the ground or any suitable place and the machine or mold removed and the cores drawn without movement of the block.

Figure 1 is a perspective view showing a mold in position to be filled. Fig. 2 is a sectional end elevation through the collapsing core. Fig. 3 is a longitudinal section through the core. Fig. 4 is a horizontal section through the core as it stands ready for tamping the material around it. Fig. 5 is a sectional elevation of the operating-plate, showing connection to the operating-rod; while Fig. 6 is a front elevation of the operatingplate alone.

-My mold consists of two sides A and A and the ends B and B, said sides and ends being flanged outward at the top to form a scraping-surface M and N, respectively. The side A is made with any suitable face X, as may be desired by the operator. Said sides A and A are also provided near their ends with feet L, which enable them to stand unsupported. Extending across the ends B and secured to the said ends by means of the bearings J is the operating-rod D, which near its ends is bent at right angles to itself, as shown at E. Said bends extending along the sides A and A are again bent downward to form a hook, as shown at F, which engages the hook-pockets Gr when the machine is set ready for tamping, as clearly shown in Fig. 1. At one end the operating-rod is provided with an extension, said extension being bent upwardly to form a handle or lever H. On the said rod D is secured the dog 2 which engages the lug 5 of the operating-plate K, so that when the said dog is thrown upward it vention, what I will move the plate upward and when drawn down will throw the plate down, as clearly shown in Fig. 5.

My collapsible core consists of the two sides C, bent together in a quarter-circle each at one end and secured by the hinges 3. To one side of the core is secured the lid S by the hinges 1, which covers up the core and prevents the material from getting inside the same. To the inner side of the sides 0 is secured a tension-spring P by the lugs 4. Also to the inner sides and at the straight ends of the sides C are secured straps 7, which extend through the opemngs R in the ends B and engage the beveled faces Q of the operating-plate K, said straps being bent at their ends 8 to the same angle as that of Q to provide a smooth sliding surface. Operatinglates K are secured to the ends B by the bolts 6, which work through the slotted holes U and allow the plate K to move upward and downward.

It will be clear t at when the lever H is thrown upward or away from the end it not only releases the hooks F from the pockets G, but it throws the operating-plate upward, which allows the straps 7 to be drawn toward each other by the spring P. In doing so the side of the core engaging the lug T will force the lid S upward, so that it may be raised by the hand, so as not to endanger the edges of the block when drawing the core.

Having thus fully described my said inclaim as new, and wish to secure by United States Letters Patent, is

1. A. mold embodying sides and ends, cores composed of two spring-pressed elements having extensions thereof projecting through openings provided therefor in said ends, and means disposed between said extensions and engaged thereby to enable said core to assume expanded and contracted po sitions.

2. A mold embodying sides and ends, collapsible cores having extensions thereof projecting through the ends, means to secure said ends and sides in locked position, and means for operating said means and for engaging said core extensions to influence the collapsed and expanded positions of said cores.

3. A mold embodying sides and ends, collapsible spring-pressed cores having portions thereof projecting through the ends, means to lock the sides and ends, a sliding wedge member engaging said core portions, and means to operate saidmember andsaid lock- 111g means ID 111118011.

4:. A mold embodying sides and ends, collapsible spring-pressed cores having portions thereof projecting through the ends, rods having hook extensions carried by the ends, pockets carried by the sides to receive said hook extensions, sliding wedge-plates engaging between the projecting portions of the cores and connections between said plates and rods to operate the same in un1son.

I 5. A mold embodying side and-end members, collapsible cores on the end members, means to lock the members together, and means for simultaneously unlocking said I members and permitting said cores to collapse.

In testimony whereof I afliX my signature 20 in presence of two witnesses.
